Mr. Raymond Cai

Mr Raymond Cai graduated from the National University of Singapore (NUS) with a Bachelor of Science (Physics) with Second Class Honours (Upper Division) under the NUS Undergraduate Scholarship, awarded to students with high academic excellence and leadership potential. During his study, he was in the prestigious University Scholars Programme (USP). In his final year; he was awarded the Outstanding Researcher Prize for his Honours thesis on Quantum Physics, now published in a reputable scientific journal – The New Journal of Physics. He was also a former straight-As student of National Junior College and Raffles Institution under the Gifted Education Programme.

Since 2003, Mr Cai has helped numerous batches of grateful JC physics students improve their H2 physics grades within a short time while gaining an in-depth understanding of the A level physics syllabus as well as recognition of the common misconceptions and difficulties that students face in the examinations. His passion for teaching has led him to since complete a Masters of Education degree with the National Institute of Education (NIE), specialising in Curriculum and Teaching to augment his teaching and pedagogy. Due to his subject mastery and ability to communicate physics effectively, Mr Cai has been approached by and has co-authored some guidebooks and assessment books with MarketAsia, Yellow Reef and Fairfield Book Publishers, and was also the consultant for Ten Year Series (Physics), in collaboration with the latter publisher.

In his teaching, Mr Cai firmly believes that Physics cannot be learned solely through the rote memorization of formulas, but that students need to see the concepts in real “action” and day to day examples to gain a deeper and more meaningful understanding. Drawing from his own experiences and knowledge of students’ different learning styles, he incorporates various features of the University Scholars Programme and Gifted Education Programme to help his students understand Physics through a rigorous multi-modal programme that is at the same time enjoyable and horizon-expanding. He also imparts to his students’ mnemonic techniques and question tackling skills that have helped many of his past students to achieve excellent grades.

Opening Quotes  The passion for your job is genuinely mirrored in your skills and abilities to be one of the most inspiring teachers I ever had. Thanks for taking the effort in making learning more fun and interesting than ever by showing us experiments on the spot. Thanks for also teaching me a subject I thought I could never understand or be interested. I hope your passion for teaching will continue to shine and inspire more people. The past 1.5 years attending your class was worth it. Thank you for being an inspiring educator and I hope to be someone like you when I grow up, making a difference in someone’s life.  Closing Quotes


Pamela Yeo, Pioneer Junior College


Opening Quotes   Mr Cai is clear in his explanations of Physics concepts during lessons, and his notes are also easy to comprehend and digest. The practice questions he set have various levels, ranging from those that test your basic understanding to those that challenge your thinking, giving students exposure to all sorts of different questions they might come across. If possible, Mr Cai will bring something cool to class to prove a Physics concept and that made the lessons more memorable for me, as I like to see what I learn in motion, how a theory works in real life. Often, Mr Cai will spend extra time after class patiently explaining something I didn’t catch earlier, and even responds to questions via messaging throughout the week, which I am incredibly thankful for, as his dedication did not falter nearing the A-level period. It is because of Mr Cai I had a chance of scoring an A for Physics in A-levels. Thank you, Mr Cai!!!   Closing Quotes


Lorraine Tan Chian Wey, Anglo-Chinese Junior College


Opening Quotes  My physics grade was a U during mid-years before I joined Mr Cai. My concepts of the topics were so weak and I couldn’t even remember the formulas or how to apply them. In school, the pace was suited for those who’ve at least a reasonably strong understanding of the content.

I would like to thank Mr Raymond Cai for his guidance in helping me catch up with the rest. His cheerful personality and amusing demos in every class never fail to make learning physics more enjoyable. More importantly, his lessons furthered my understanding of each topic through a variety of questions so that I know how each segment of the syllabus can be tested.   Closing Quotes
